The correct answer is stiff neck, fever, mental status change, photophobia. These symptoms are commonly associated with meningitis. Stiff neck refers to the difficulty in moving the neck due to inflammation of the meninges. Fever is a common symptom of an infection, including meningitis. Mental status change refers to alterations in consciousness, behavior, or cognition, which can occur due to the inflammation affecting the brain. Photophobia, or sensitivity to light, is another common symptom of meningitis. The other options mentioned in the question, such as hypoxia, low temp, high blood sugar, renal failure, and DM, are not typically associated with meningitis.

Bradykinesia refers to a condition characterized by the slowness of movement. It is commonly associated with Parkinson's disease, where individuals experience a significant decrease in the ability to initiate and perform voluntary movements. This slowness can affect various motor functions, including walking, writing, and even facial expressions. Therefore, the statement "Bradykinesia means slowness of movement" is true.

Seizures can occur in various positions, but if someone is having a seizure, it is generally recommended to help them lie on their side. This position helps prevent choking by allowing any saliva or vomit to drain out of the mouth. It also helps keep the airway open and reduces the risk of injury during the seizure. Therefore, the statement that "seizures need to be lying on side" is true.

The brain stem is responsible for controlling vital functions in the body, such as breathing, heart rate, and blood pressure. It connects the brain to the spinal cord and regulates various involuntary actions that are necessary for survival. Therefore, it is correct to say that the brain stem is involved in controlling all vital functions.

Dysphagia refers to difficulty in swallowing, which can increase the risk of aspiration. Aspiration occurs when food, liquid, or saliva enters the airway and lungs instead of going down the esophagus into the stomach. This can lead to choking, pneumonia, and other respiratory complications. Therefore, it is true that dysphagia poses a significant risk for aspiration.

The statement is true because CT scan is usually performed before a lumbar puncture (LP) in cases of suspected encephalitis. This is because a CT scan can help identify any structural abnormalities or bleeding in the brain that may increase the risk of complications during an LP. Additionally, a CT scan can provide valuable information about the patient's condition and guide further diagnostic and treatment decisions. Therefore, it is recommended to perform a CT scan before proceeding with an LP in cases of encephalitis.

A swallow study is necessary for patients before they can eat because it helps assess their ability to swallow safely and effectively. This study involves observing the patient's swallowing process using imaging techniques such as X-rays or fluoroscopy. It helps identify any potential issues or abnormalities in the swallowing mechanism, such as difficulty in swallowing or risk of aspiration. By conducting a swallow study, healthcare professionals can determine the appropriate diet and feeding techniques for the patient, ensuring their safety and well-being while eating. Therefore, it is true that patients need a swallow study before they can eat.

The statement "stroke[Cardiac exam (info about arrhythmias, carotids)]" is true. This means that during a cardiac exam, information about arrhythmias and carotid arteries can provide insights into the risk of stroke. This is because arrhythmias, such as atrial fibrillation, can increase the risk of blood clots forming in the heart, which can then travel to the brain and cause a stroke. Additionally, assessing the carotid arteries can help identify any blockages or narrowing that could contribute to stroke risk. Therefore, it is important to include these aspects in a cardiac exam to evaluate stroke risk.

This statement is false. Thrombolytics are medications used to dissolve blood clots. They are typically used in conditions such as heart attacks or strokes. Having high blood pressure is actually a contraindication for the use of thrombolytics because it can increase the risk of bleeding. Therefore, it is not necessary to have high blood pressure for the use of thrombolytics.

EEG stands for electroencephalogram, which is a test that measures electrical activity in the brain. It is a non-invasive procedure that involves placing electrodes on the scalp to detect and record the brain's electrical signals. By analyzing these signals, doctors can diagnose various brain disorders such as epilepsy, sleep disorders, and brain tumors. Therefore, the statement "EEG is for the brain" is true, as it accurately describes the purpose and function of EEG in studying brain activity.

Parkinson's disease is a neurodegenerative disorder that primarily affects movement. One of the early symptoms of Parkinson's disease is unilateral weakness, meaning weakness on one side of the body. This can manifest as a slight tremor or difficulty performing tasks with one hand. As the disease progresses, the weakness may spread to both sides of the body. Therefore, it is true that a Parkinson's patient often starts with unilateral weakness.

Parkinson's condition worsens when the level of dopamine in the brain drops. Dopamine is a neurotransmitter that plays a crucial role in regulating movement and coordination. In Parkinson's disease, the cells that produce dopamine in the brain gradually degenerate, leading to a decrease in dopamine levels. This deficiency of dopamine results in the characteristic symptoms of Parkinson's, such as tremors, stiffness, and difficulty with movement. Therefore, when the dopamine level drops, the symptoms of Parkinson's worsen.

Meningitis is a condition that causes inflammation of the membranes surrounding the brain and spinal cord. It can lead to a range of symptoms including headache, fever, stiff neck, and sensitivity to light. The question is asking which of the given signs have "brudy kerng," which is likely a misspelling or a term that is not commonly used or recognized. Without further information, it is not possible to determine what "brudy kerng" refers to in relation to meningitis.

The statement is true because the sugar levels in the brain are indeed lower than the sugar levels in the bloodstream. The brain relies on glucose as its primary source of energy, and glucose is transported to the brain through the bloodstream. However, the brain has a unique barrier called the blood-brain barrier that regulates the passage of substances, including glucose, from the bloodstream into the brain. This barrier ensures that the brain receives a steady supply of glucose but at a slightly lower concentration compared to the bloodstream.

LP, which stands for lumbar puncture, is a procedure used to confirm a case of meningitis. During an LP, a needle is inserted into the lower back to collect cerebrospinal fluid (CSF) for analysis. Meningitis is an infection or inflammation of the membranes surrounding the brain and spinal cord, and CSF analysis is crucial in diagnosing the condition. Other diagnostic tests, such as blood tests or imaging studies, may provide supportive evidence, but LP is considered the definitive method for confirming meningitis. Therefore, the statement "LP is the only way to confirm a case of meningitis" is true.

The correct answer is bacterial because the patient had a traumatic brain injury and underwent neurosurgery, during which an intraventricular catheter was placed. These procedures increase the risk of bacterial infection, as bacteria can enter the brain through open wounds or medical devices. Therefore, it is likely that the patient's infection is caused by bacteria.

The statement "TREAT FAST. can not give thrombolytic if more than 4.5 hours" is true. Thrombolytic therapy is a treatment used to dissolve blood clots in certain medical conditions, such as ischemic stroke. However, it is time-sensitive and should ideally be administered within 4.5 hours of symptom onset. Beyond this time frame, the risks of bleeding complications outweigh the potential benefits of thrombolytic therapy. Therefore, if more than 4.5 hours have passed since the onset of symptoms, thrombolytic therapy is not recommended.

Parkinson's disease is not diagnosed by lab values alone. The diagnosis of Parkinson's disease is primarily based on the presence of specific symptoms, such as tremors, stiffness, and impaired balance, along with a thorough medical history and physical examination by a healthcare professional. Lab tests may be ordered to rule out other conditions that can cause similar symptoms, but they are not definitive for diagnosing Parkinson's disease. Therefore, the correct answer is False.

A Glasgow Coma Scale (GCS) score of less than 8 indicates a severe brain injury. The GCS is a neurological scale that assesses a person's level of consciousness after a brain injury. It evaluates three areas: eye opening, verbal response, and motor response. A score of 8 or lower suggests that the person has a significantly impaired level of consciousness and is likely to have severe brain damage.

The statement "there is not a known meningitis vaccine" is false. There is a known meningitis vaccine available. Meningitis is a serious infection that can cause inflammation of the membranes surrounding the brain and spinal cord. Vaccines have been developed to protect against certain types of meningitis, such as meningococcal meningitis. These vaccines are recommended for certain age groups and individuals at higher risk of infection, such as college students living in dormitories or people traveling to regions with high rates of meningitis. Therefore, the correct answer is false.

Based on the information provided, Jenny Oko has been experiencing symptoms of an enterovirus for several weeks. Enteroviruses are a type of virus that can cause various illnesses, including respiratory and gastrointestinal infections. Since the question asks for the type of infection Jenny is likely experiencing, the correct answer is "viral" as enteroviruses are caused by viral infections.

Keeping blood pressure high in stroke patients is not recommended. The correct answer is False. High blood pressure can further damage the blood vessels in the brain and increase the risk of another stroke. It is important to control blood pressure in stroke patients to prevent complications and promote recovery.

Parkinson medication should not be held before surgery. This is because abruptly stopping Parkinson medication can lead to a sudden worsening of symptoms, known as "off" periods, which can be very uncomfortable for the patient. It is important for the patient to discuss with their healthcare provider about the management of their medication before any surgery to ensure a smooth transition and minimize any potential complications.

The given answer suggests that low glucose, low oxygen, high CO2, thiamin deficiency, and possibly narcan can mimic a stroke. These conditions can cause symptoms similar to those seen in a stroke, such as neurological deficits and altered mental status. Low glucose levels can impair brain function, while low oxygen levels can lead to brain damage. High CO2 levels can cause respiratory distress and affect brain function. Thiamin deficiency can result in neurological symptoms, and narcan, which is used to reverse opioid overdose, may cause transient neurological deficits. These conditions should be considered when evaluating a patient with stroke-like symptoms.

This answer suggests that the factors mentioned (sudden and extreme, higher fever/rash, lives in prison or dorm, tight quarters, anything manipulating the brain) are associated with the spread of measles. These factors can contribute to the rapid transmission of the virus in confined spaces where people are in close contact with each other. Additionally, the symptoms of measles include sudden and extreme fever and rash, which can be more severe in individuals who have not been vaccinated.

The nursing concerns with Parkinson's disease include depression and falls. Depression is a common symptom of Parkinson's, as the disease affects the brain's neurotransmitters and can lead to changes in mood and emotions. Falls are also a significant concern, as Parkinson's can cause balance and coordination issues, making individuals more prone to accidents and injuries. These nursing concerns require careful monitoring and management to ensure the well-being and safety of patients with Parkinson's disease.

A hypotonic solution has a lower concentration of solutes compared to the fluid within cells. This means that water will move into the cells, causing them to swell and potentially burst. In the context of stroke, a hypotonic solution would exacerbate the condition by increasing swelling and further damaging brain tissue. Therefore, a hypotonic solution is not suitable for stroke treatment.

The given information states that Blake Calahan has been diagnosed with cryptococcol infection of the upper respiratory system. Cryptococcosis is a fungal infection caused by the Cryptococcus fungus. Therefore, the correct answer is fungal.

The cranial nerves that are commonly affected in meningitis are III (oculomotor), IV (trochlear), and VI (abducens). These nerves are responsible for controlling eye movements. Meningitis is an inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. Inflammation in this area can cause pressure on the cranial nerves, leading to symptoms such as double vision, difficulty moving the eyes, and eye muscle weakness. In severe cases, other cranial nerves like VII (facial) and VIII (vestibulocochlear) may also be affected, causing facial weakness and hearing loss.

Treating high blood pressure in a stroke patient may be avoided because high blood pressure helps maintain perfusion to the brain. When a stroke occurs, blood flow to the brain is compromised, and maintaining adequate perfusion is crucial to prevent further damage. High blood pressure helps to ensure sufficient blood flow to the brain, compensating for the reduced blood supply caused by the stroke. Therefore, treating high blood pressure in this context may potentially worsen the patient's condition by further reducing perfusion to the brain.

Too high dopamine levels in Parkinson's disease can lead to the wearing off or stoppage of medication effectiveness. This is because the body may become less responsive to the medication over time, causing it to lose its effectiveness. Taking the medication at the same time every day is important to maintain a consistent level of dopamine in the body and optimize its effectiveness. Deviating from the regular schedule may result in fluctuations in dopamine levels, leading to reduced symptom control.

The explanation is that visual examination alone is not sufficient to distinguish between viral and bacterial meningitis. Spinal fluid labs are necessary to accurately diagnose the type of meningitis.
